Biodiesel Production from cottonseed oil by micro-flow system

摘要

Currently, continuous synthesis of biodiesel has been widely studied due to a series of problems imposed by biphasic reaction and thermodynamic, as well as to reduce production costs. In this work, transesterification of cottonseed oil to biodiesel was carried out in a microtube reactor with a micromixer. The effects of molar ratio of ethanol to cottonseed oil, reaction temperature and residence time had been experimentally discussed. The optimal result was obtained under the conditions of oil-to-ethanol molar ratio of 1:16, a residence time of 7min, and a temperature of 70°C.
